You hardkilled.  Of course it should bring down everything.  If you
don't want to hardkill, then disable specific radios via /sys or some
UI.  The hardswitch is the "eject" button.

Other types like pushbutton switches (Fn+F5, HP laptop touchbuttons,
etc) that *aren't* hardswitches connected to a GPIO on the wifi device
should probably just bring up some window letting you pick what gets
rfkilled.
